Taylor Water Hardness & Quality Report (2026)

Taylor, Texas, in Williamson County — a Williamson County city adjacent to Georgetown and Granger in the north Austin metro — receives its municipal water from the Taylor Water Division, drawing from the Little River system or Lake Georgetown (San Gabriel River, Williamson County) through the Taylor treatment system.

The very hard 280.5 mg/L hardness and elevated TDS of 753 mg/L reflect the Williamson County Texas Hill Country-Coastal Plain transition's intense calcareous character. The San Gabriel River at Williamson County drains the Texas Hill Country — Cretaceous Edwards Group limestone (the dominant Texas Hill Country carbonate platform — very high purity limestone), Cretaceous Del Rio Clay and Georgetown Limestone (calcareous), and Pennsylvanian Strawn Group (calcareous-evaporitic). The cumulative Cretaceous limestone and Pennsylvanian evaporitic loading produces the very hard Williamson County supply.

At 280.5 mg/L, Taylor's water is very hard. A water softener is strongly recommended. Scale builds rapidly on all heating surfaces, appliance lifespans are significantly shortened, and water heaters require annual descaling without softening. The PFAS level of 9.0 ppt warrants a certified reverse osmosis drinking water filter — the Williamson County north Austin metro industrial corridor (Samsung Austin Semiconductor and other major Williamson County electronics manufacturers are significant PFAS users), and the north Austin metro PFAS background contribute to Taylor's elevated readings.
